LIFTlNG-GUARD FOR MOWING OR OTHER AGRICULTURAL MACHINES.

SPECIFICATION forming part of Letters Patent No. 727,576, dated May 12, 1903.

Application fileil January-l7, 1903. Serial No. 139.427. (No model.

To all whom it may concern:

Be it known that I, FRANZ-BLOCKI, a citizen of the United States, residing at Sheboygan,

in the county of Sheboygan and State of \Vis-.

consin, have invented certain new and useful Improvements in Lifting-Guards for Mowing or other Agricultural Machines; and I do hereby declare that the following is a full, clear, and exact description of the same, ref erence being had to the annexed drawings, making a part of this specification, and to the letters of reference marked thereon.

The present invention has relation to that class of devices or attachments to harvesters or mowers to be used in down grain and adapt itself to the unevenness of the ground; and the object thereofis to provide a simple and effective device of the above character that will possess strength and durability and be effective in its purpose.

The invention consists in an attachment to harvester machines, constructed substantially as shown in the drawings and hereinafter described and claimed.

Figure 1 of the drawings is a perspective view of the attachment, showing it connected to the arm of a harvesting-machine; Fig. 2, a side elevation, partly in section.

In the accompanying drawings, A repre sents the projecting arm of a harvesting-machine, to which are connected the usual fingerbar B and knife-guard C, said guard being seated in the groove in the arm and held at its point by a grooved clamp D, with which the point of the guard engages. This clamp is secured to the projecting arm A by means of a bolt Ct and a nut b, engaging the screwthreaded end of the bolt, or other suitable means may be employed for holding the clampin place, and the clamp may be of any preferred construction found best adapted to the purpose, the several parts herein described being subject to many changes and modifications as circumstances would require, a bolt 0 and nut (Z connecting the arm A and fingerbar together.

The arm A has a curved extension 6 at its outer end, to which is suitably pivoted the attachment comprising the lifter-guard E, which may be of any suitable construction and form,as found most desirable. In the present instance the lifter-guard E is pivotally connected to the curved extension by a nutf and bolt '9, or any other suitable means may be substituted for forming a pivotal connection of the lifter-guard with the curved extension of the arm. A suitable spriug,either fiat or other form, is suitablycouuected to the end of the curved extension 6, said spring beingindicated at F, and one of many means that may be employed comprises the bolt h and nuts 2' 7', as shown in Fig. 2 of the drawings.

The lifter-guard E is cast or otherwise provided with double wings G, which embrace the curved extension 6 of the arm A, upon both sides thereof, thereby increasing the strength and durability of the lifter-guard and bracing it upon both sides of the curved extension of the arm, as well as forming a guide for the lifter-guard. The lower extremity of the wings G have elongated slots 70, through which passes the bolt Z, and engaging with the screw-threaded end of said bolt is a nut m. This is one of many means that may be employed for regulating the adjustment of the lifter-guard. The spring which renders the lifter-guard spring-actuated keeps the point of the lifterto the ground as adjusted, and when striking an obstruction the spring will allow the lifter-guard to yield thereto. The adjustment of the lifterguard F through the medium of the bolt Z, extending through the elongated slot Z6, and the nut upon the bolt provide means whereby the dip or the position of the point of the lifter-guard may be regulated if the point of the knife-guards are not in line. The bolt Z normally rests against the lower part of the curved extension 6, as shown in Fig. 2 of the drawings, thereby forming a stop to limit the downward swing or travel of the lifterguard E. v p

The spring-actuated lifter-guardand the construction thereof, as well as the means for regulating the downward swing or travel of the lifter-guard, provides a finger-guard with relation to that of the knife-guard, provides a simple and effective device that may be conveniently attached to harvesters, mowers, or other agricultural machines Where such an attachment would be required, such device or attachment possessing both strength and durability, and it being spring-actuated and the position of the lifter-guard being capable of adjustment renders the guard efiective in its action.

I claim-- 1. Alifter-guard for mowing or other agricultural machines, an arm projecting from the machine and pivotally supporting said guard, a spring connected to the arm and having its free end bearing against the under side of the guard, and wings depending from the guard and embracing the end of the arm and having elongated slots, and means for engaging the slots to regulate the downward swing or travel of the guard, substantially as and for the purpose set forth.

. 2. A spring-actuated lifter-guard for mowing or other agricultural machines, an arm waste
